摘要：
The microwave reflection loss (RL) of four series of synthesized ferrites, Ba0.5Sr0.5CoxZrxFe(12 - 2x)O19 and Ba0.5Sr0.5CoxTixFe(12 - 2x)O19, have been measured using network analyzer in the frequency range from 8.2 to 12.4 GHz. The comprehensive analysis of RL is carried out as a function of substitution, frequency, and thickness. The various models contributing to large RL are described. The composition accompanying maximum microwave absorption is suggested. (C) 2012 Wiley Periodicals, Inc.
